Track a project pre-commit hook under scripts/hooks/ that regenerates
openapi.json when server source is staged, and auto-stages the updated
spec into the commit. Zero external dependencies — plain bash + cargo.
Enable via `git config core.hooksPath scripts/hooks`. The CI drift
test remains the authoritative check.
